IUF 5km competition - which 24" unicycle

[one]

Racing unicycles

In terms of the actual unicycle, if I were thinking of racing the 24" class. Is there much difference between a 24x2 compared to, for example, the mad4one uni with the 26x1 tyre? I’ve never ridden a tyre that narrow! There are other differences of course, the m4o uses a narrower hub for instance. Does it feel much different to ride?
